A non-asbestos friction material contains a fibrous substance, a binder, and a friction modifier. The material contains no copper components, no carbonaceous raw materials, and no metal sulfides but contains an inorganic material having a laminar crystal structure and being different from the copper components, the carbonaceous raw materials, and the metal sulfides. Preferably, the inorganic material is at least one inorganic material selected from titanates, talc, kaolin, mica, vermiculite, and smectite.

A brake disc structure contains: a central disc made of metal material or metal alloy material, a first disc and a second disc which are made of ferrous metal materials, and a through orifice passing through central positions of the first disc, the central disc, and the second disc. The first disc includes a first brake face and plural first holes, the second disc includes a second brake and plural second holes, and the central disc includes plural third holes, wherein each of the plural first and second holes has a first diameter and a second diameter less than the first diameter, and diameters of any two adjacent first and second holes are different. Furthermore, multiple heat dissipation portions of the central disc are defined by the plural third holes and the plural first holes or are defined by the plural third holes and the plural second holes.

A damper device is provided with a first rotating body, a second rotating body, a coil spring and a spring seat. The coil spring is interposed in a circumferential direction between the first and second rotating bodies. The resin spring seat includes a metallic core member inside. The resin spring seat has a seat portion and an overhang portion. The metallic core member has an overhang metallic core part that has a low-rigidity portion and a high-rigidity portion. The low-rigidity portion is provided on a side close to the seat portion with a relatively lower rigidity. The high-rigidity portion is provided on a side far from the seat portion with a relatively higher rigidity.

A composite driveshaft includes a body having a first end, a second end, and an intermediate portion defining a driveshaft axis (DSA). The first end defines a first coupling region and the second end defines a second coupling region. At least one of the first and second coupling regions defines a virtual hinge configured to accommodate both bending moments and axial changes of the body.

This invention relates to a paper friction material and a method of manufacturing the same, wherein the paper friction material is configured such that dispersibility and bondability are increased between a filler and a matrix. The paper friction material which is suitable for use in a vehicle, includes a friction base including pulp and a coating layer formed on the friction base using a mixture of latex and a functional material. The OH reactive group of the pulp and the aromatic ring of the latex are hydrogen-bonded so that the friction base and the coating layer are coupled with each other.
